Overview
SIST EN ISO 2738:2026 is an international standard developed by CEN and ISO. It specifies methods for determining the density (both dry and fully impregnated), oil content, and open porosity of permeable sintered metal materials, excluding hardmetals. These test methods play a crucial role in quality assurance for powder metallurgy, particularly for porous metal bearings and structural parts created through pressing and sintering metal powders. Consistent measurement of these properties supports manufacturing efficiency, reliable product performance, and conformity with global trade requirements.
Key Topics
Applications
-
Powder Metallurgy Bearing Quality:
SIST EN ISO 2738:2026 is essential for manufacturers of porous metal bearings, enabling them to maintain consistent density, oil content, and porosity-key to reliable lubrication and longevity in operation.
-
Sintered Structural Parts:
The standard is widely applied in industries producing sintered metal components for automotive, industrial, or consumer products. Accurate determination of porosity and density ensures conformity with performance specifications.
-
Research and Development:
Laboratories and R&D departments use the standard to validate material properties, optimize powder composition, and improve sintering processes.
-
Quality Control and Certification:
Compliance with SIST EN ISO 2738:2026 supports certification processes, supplier qualification, and meets procurement requirements in supply chains demanding documented material characteristics.
